deployments: Add CDI spec examples

Add example CDI specifications for testing and reference.

Files:
- cdi-spec-a100-2gpu.yaml: Minimal 2-GPU configuration
  - Lightweight setup for development/testing
  - Includes environment variable examples
  - Demonstrates basic CDI structure

- cdi-spec-a100-8gpu.yaml: DGX A100 simulation
  - 8x NVIDIA A100-SXM4-40GB GPUs
  - Matches default mode topology
  - Shows complete device enumeration
  - Includes usage instructions in comments

Both specs follow CDI v0.5.0 specification and include:
- Device nodes (/dev/nvidia0-7, nvidiactl, nvidia-uvm*)
- GPU model annotations for architecture detection
- UUID and index metadata
- Proper device major/minor numbers

Usage:
  # From file:
  kubectl create configmap my-spec \
    --from-file=spec.yaml=cdi-spec-a100-2gpu.yaml
  helm install gpu-mock ./helm/gpu-mock \
    --set cdi.enabled=true --set cdi.configMapName=my-spec

  # Inline:
  helm install gpu-mock ./helm/gpu-mock \
    --set cdi.enabled=true \
    --set-file cdi.inlineSpec=cdi-spec-a100-8gpu.yaml

These examples serve as templates for creating custom GPU topologies.
